  2. B \(\mathrm{N}_2 \mathrm{O}\)
  3. C \(\mathrm{N}_2 \mathrm{O}_5\)
  4. D \(\mathrm{NO}_3\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\mathrm{NO}\)

Step-by-step Solution

Detailed explanation

When copper metal is treated with cold and dilute nitric acid. It yields copper nitrate, water and nitric oxide. \(3 \mathrm{Cu}+8 \mathrm{HNO}_3(\) dil. \() \longrightarrow 3 \mathrm{Cu}\left(\mathrm{NO}_3\right)_2+4 \mathrm{H}_2 \mathrm{O}+2 \mathrm{NO}\)
